The trials is a number of challenges testing skill, strength, stealth, and cunning. It contains of the the jumping trial, the darkness trial, the water trial, the nature trial, and the fire trial. It was made by Snowkit
After completian of the trials, you come across a diamond room with prizes in chests like for instance cake. You also come across the clubhouse made by Coheed14 which contains a theater, a jacuzzi, and more.
Also near the trials, there is an extreme jumping challenge that can help you with completian of the jumping trial and the soul sand beach trial. This challenge is just like the trial, but instead of falling onto stone like the jumping trial you fall, just like the soul sand beach trial, into lava.
In the Nether, you can find the nether trials. Instead of the trials being inside rooms this is more like one path. It consists of the fire climb trial, the burning water trial, the pigmen house trial, the ghastly glowstone trial, the netherrack woods trial, the soul sand beach trial, and the mushroom riddle trial. It was made by Dineseer.
Also new are the sky trials. Unlike the other trials, you can choose your path, so you won't do all of the trials to acheive completian. All of these trials take place in the clouds. So far it only consists of the milky dreams trial and the magical hunt trial.
